Which is better for electric vehicle lithium battery or lead-acid battery?

Electric vehicles have been developed for more than 20 years. They are convenient and fast and are loved by users. With the improvement of battery technology, the range of electric vehicles is getting farther and farther, from the earlier lead-acid batteries to the lighter lithium batteries. People have more and more choices. Although everyone knows that lithium batteries have higher energy density, lead-acid batteries are more durable and safer than lithium batteries. How do we choose the type of electric vehicle battery? Which is better, lithium batteries for electric vehicles or lead-acid batteries? With the renewal and iteration of battery technology for electric energy vehicles, the development of lithium batteries has a tendency to rise from the safflower double stick to the leader of the community. However, it has only risen. Limited by its own performance, cost-effectiveness and other reasons, there is still a long way to go to replace the status of the lead-acid battery, and the lead-acid battery is constantly making self-breakthroughs. Today’s weather is good, so Lao Na (who accidentally said it was leaking) will take you to the inspectors to learn about the safflower double stick (lithium battery) and the boss (lead-acid battery) in the battery club. Continuously, those of you who are at work and waiting for your exam results, don't forget to go home and collect your clothes. So let's start with lead-acid batteries: the ancestral knowledge of lead-acid batteries 1. The golden bell iron cloth shirt (hard!) The lead-acid boss has always been in line with him to make him strong, and the breeze caresses the hills. He arbitrarily let him arbitrarily, the bright moon shines on the river as the principle. The lead-acid battery is easy to feed, so you can be beaten and beaten. You can continue to use it after a little repair. 2. The price of cabbage (cheap!) The reason why the lead boss has been able to cross the battery community for many years and sit in the position of the boss is all for this reason! Cheap, in addition to cheap or cheap. 3. Recasting (recyclable and reversible repair) lead-acid batteries have their own recyclable skills. After they are worn out, you can go to the electric car shop to exchange the old for a new one. If you make up the price difference, you can change to a new set of batteries to minimize the loss. It is not a small benefit for users. Now that we have talked about fascination, let’s take a look at the shortcomings of lead-acid batteries: large volume and weight, limited battery capacity, and short life. Lead-acid batteries generally have a deep charge and discharge within 400 times, with memory, and a lifespan of about two years. . The ancestral knowledge of lithium batteries 1. The ancestral light work (light weight and small size). Compared with the lead-acid batteries of the same capacity on the market, the volume of the lithium battery is 2/3 of the volume of the lead-acid battery, and the weight is light. About 1/3 of the weight of a lead-acid battery. Lithium batteries of the same volume have a higher capacity than lead-acid batteries, and the reduction in weight increases the endurance of electric vehicles by about 10%. 2. Durable health maintenance (increased lifespan) Lithium batteries are the best way of health preservation. The average lifespan of lithium batteries is about 4 years, which is about 1.5 times longer than that of lead-acid batteries. The battery is charged and discharged more than 500 times. The battery has no memory and is shock resistant Strong. 3. The ancestral qigong spitting method (overcharge resistance, good charge and discharge resistance) lithium batteries have been opened up through the eight pulses of the odd meridian since childhood, so that under normal temperature, the lithium battery can be continuously charged for 48 hours without battery expansion, leakage and rupture Wait for the accident, the capacity remains above 95%. And under the special charger, it can charge and discharge quickly. Although lithium batteries have many advantages, their disadvantages are also more obvious. The production cost of lithium batteries is high. The expensive production equipment and labor costs account for about 40% of the production cost, and the price is about three times that of lead-acid batteries. The price-performance ratio brought by its triple price is not high, and it is quite flashy, and the lithium battery is not recyclable. If it is worn out, it can only be thrown away, or it can be buried somewhere. After thousands of years, later generations will dig it. It's an antique when it comes out. The most important problem is that lithium batteries have a fire and explosion safety hazard, especially when consumers are deceived by profiteers without their knowledge to buy low-quality lithium batteries. The sealing conditions in electric vehicles are not very good, and they are easy to be exposed to moisture. Poor and other reasons may cause potential safety hazards. However, the technical performance of lithium batteries is constantly improving, and high-safety materials are being used. The potential safety hazards may be just unnecessary worries for the author. Perhaps it will be the world of lithium batteries in a long time. Disclaimer: Some pictures and content of the articles published on this site are from the Internet.
